I guess I'll jump in. This topic seems like a stretch even for Around the Campfire. Anyways...

1) Wash your face with good soap and hot water, daily.
2) Go to the drug store and pick up acne treatment.
3) Visit a dermatologist.

Not sure where you heard to apply iodine to your zits. Something about that doesn't sound right to me. If you eat a lot of greasy, processed foods it might help to cool it. Lay off the pizza, soda, fries, etc.

You mention not wanting to "...spend lots of money on fancy cream crap." If you're suffering from acne so badly that you are asking us here on the forums for advice, perhaps suggestion #3 above is in order.
